THOMAS MESSENGER DROWN, OE PHILADELPHIA, PENNSYLVANIA, AS

SIGNOR TO W. A.DROWN,.OE SAME PLAGE.

Letters Patent No. 110,907, dated January 10, 1871.

The Schedule referred to in these Letters Patent and making parl: of thesame.

I, THOMAS MESSENGER Dnows, of Philadelphia, county of Ihiladelphia,State of Pennsylvania, have invented an Apparatus for Dyeing orImpregnating Fabrics, of which thc' following is a speciiication.

Nature (tml Object of the Invention..

My invention consists ofap1'ia1'atus,too fully dcscribed hereafter toneed preliminary explanation, for dyeing or water-proofing fabrics, thcmain object of my invention being the impregnation of theV fabricswithout exposing much of the liquid to air and light,`

thereby preventing the rapid evaporation or deterioration of theliquid,and when the latter is of an inflammable character of preventingaccidents from ignition.

Description of thc Accompanying Drawing/5 Figure 1 isI a sectionalperspective view of my `in1- proved apparatus for dyeing or impregnatingfabrics; and Y Figure 2, a planvicw of the same.

General Description.

A represents a rectangular box provided with a hinged lid, a, andcontaining au angular reservoir, B.

The fabric to be treated is passed through a.slit, b, in the'top of thebox, umleraroller, c, arranged near the bottom of the reservoir, thenbetween pressing and drawing-rollers, h h, above the reservoir, andlinally through a slit, b, in the front of the box.

rIhe drawingr and pressing-rollers h li. are geared together at one orboth ends so that they maybe operated simultaneously, and are containedwithin the box' above a shelf or partition, t', which maybe slight-lyinclined or otherwise arranged in such a manner as to conduct back intothe reservoir the superfluous liquid expressed from the fabric inpassing between the rollers.

lhe reservoir is supplied with a sufficient quantity of the liquid, withwhich the fabric is to be treated, to cover the roller c, by a pipe, j,which enters the reservoir beneath the said roller and'communicates withthe lower part of a closed tank, C, arranged at such a height above thesaid reservoir as to enable the liquid to iiow into the. same by its owngravity.

A pipe., K, also extends from ythe top of the said tank into thereservoir, and terminates within the latter at a point coinciding withthe desired height of the liquid.

This pipe is designed to supply air to the tank as therliquid tlows fromthe latter through the pipej into thereservoir.

When the liquid rises in thereservoir to a point above the open endofthe said pipe It, the ow through the pipe j must cease until the levelof the liquid again descends so as to enable air to enter the tank. Thusa constant and uniform self-regulating supply of liquid, at anydetermined level, can be maintained in the reservoir.

lBoth of `the pipes j and It are furnished with stopcocks, m, so as toenable the supply of iiqnid to the reservoir and of air to the tank tobe cut off at any time; and the said pipes, which can be flexible ifdesired, may be of any length, according to the position of tbe tank inrespect to the reservoir, which may be placed''at a considerabledistance from the tank to avoid accidents where the liquids employed aretia light inflammable nature.

-The above apparatus has been designed especially for dyeing fabricswith materiulswhich would be injured by'exposnre to the air or light,and also for impregnating fabrics with substances held in solutionin'volatile liquids, such, for instance, as spermaceti dissolved inbenzine or naphtha for waterlprooting purposes.

,Ihe advantages of the apparatus for such purposes may be brieflydescribed as follows:

The closed box or vessel prevents deteriorationof the liquids employedby direct exposure to air or light,A

and also'prevents the escape of the vapors of volatile liquids.

The arrangement of the pipes in respect to the'tank 'and reservoirprevents unnecessary exposure or loss of liquid by'maintaiuing asuiicient but comparatively small quantity of the latter in thereservoir.

. The arrangement of pipes, and the fact that the tank, with which theyare connected, can be at'any cle-,-

sired distance from the reservoir, also permit-s benzine and similarinflammable substapces to be used with perfect safety.

lhe arrangement 'of the drawing and pressingrollers within the box andabove thcreservoir also 'prevents unnecessary loss of liquid, as all ofthe matter which is expressed from the fabric in passing between thesaid rollers can dow back into the reservoir.

Claims.

l. A reservoir, containing volatile impregnating material, closed toprevent the evaporation of the said material,-`bnt slit at two points topermit the passage through it of a strip of fabric to be impregnated, asset forth.

2. The combination of said reservoir and a tank, c, communicating withthe reservoir, as described In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.'4 l
